Maytag Gas Dryer doesn't heat up

Maytag gas dryer has been operating at a much lower heat for a few days since I noticed that the timer stopped advancing in the more/less dry cycle. It's not the time because I replaced it and the heat has since stopped. What needs replacing: the coils? And how do I check this before I replace?

The igniter is the part that ignites the gas in the Maytag gas dryer. Long time a go the dryers use to have a pilots. The pilots where on all the time, even when the dryer was not been use.

This wasted a lot of gas and a new design was needed. That is when the igniter or glow bar as is also known, came to be. A bad igniter could be the reason for your Maytag gas dryer not heating.




The radiant sensor is a small black box that attaches to the combustion funnel. The job of the radiant sensor is to allow the igniter to glow until it is real hot, then it shuts the igniter off and opens the gas valve to start the heating process. A bad radiant sensor could the the reason for your Maytag gas dryer not heating.




The gas valve has two coils or solenoids. These coils job is to open the gas chambers inside of the gas valve.

When one of the coils goes bad, the symptom is that the igniter glows, but the gas valve won't open to let the gas flow through the gas chamber to be ignited.

A bad set of coils could be the reason for your Maytag gas dryer not heating.




The hi-limit thermostat is located on top of the combustion funnel, and its job is to open the circuit to the gas valve if the airflow to the dryer is restricted for any reason.




The cycling thermostat is use to control the temperature inside of the dryer. It is factory preset at 155 degree, in other words it will open the circuit to the gas valve when the temperature reaches 155 degrees.

This thermostat is opening and closing all the time the dryer running. A bad cycling thermostat could be the reason for your Maytag gas dryer not heating.




The timer is the part that direct the electricity to the other parts in the dryer. This part works very hard and the contacts wear out and some times they burn out. If the timer contacts won't close, the dryer will not heat.




The motor switch is another safety device that only closes the heating circuit when the motor is running. When the motor is not running the circuit of the gas valve is open and the dryer will not heat. A bad motor switch could be the cause for your Maytag gas dryer not heating.

As you could see, there are a lot of parts inside of the dryer that have to be in good working condition for the dryer to produce heat.

Maytag DG410 gas dryer-no flame, no heat. I replaced the ignitor - that apparently isn't the problem. Other ideas?


Motor runs, but main burner will not ignite
1.heat switch set wrong---correct switch setting
2.defective timer or timer circuit---check timer wiring--replace timer motor or switch as needed
3.defective centrifugal switch in motor---clean switch or replace as needed
4.gas supply valve closed----open gas valve
5.inoperative solenoid coil---test coil for open circuit & the voltage to it
???
Pilot burner goes out
1.insufficient gas supply---- low gas pressure or clogged pilot filter or partially closed gas valve
2.carbon deposit on thermocouple tube---clean tube & check pilot burner for proper combustion
3.improperly adjusted pilot flame--adjust pilot flame until faint yellow tip begins to appear
4.faulty ignition or reset valve or thermocouple---replace

Clothes not drying, but dryer runs & heats
1.defective operating thermostat---test thermostat, replace if defective
2.fan or it's pulley loose on shaft---tighten set screw
3.incorrect heat or timer settings---reset timer
4.clothes to wet when placed in dryer----wring out or extract water from clothes before placing in dryer
5.clogged lint screen or duct (little air motion)---clean out lint screen & duct

Sg7800 maytag dryer stopped giving heat


Sounds like burner not igniting. On front of dryer in the lower right there should be a gas valve/burner access panel. Usually you just have to pry out at bottom of panel & swing out and up to remove. This gives you access to valve coils and igniter. With panel removed set timer for heated dry and start dryer, observing first the igniter which should glow bright orange-red, then after a couple seconds you should hear a "Click" which is gas valve opening and a blue flame ignites for heat. If no glow is seen after a few seconds or at least a minute, igniter is bad, if it does glow and no click is heard from the gas valve, the coils (electro magnets) on the valve are bad, or the "Flame present" sensor is bad. Chances are it's either the coils or igniter.Try this on all heat settings, if you get heat at only one setting it might be in timer contacts, but not common. Again you can repair/replace both the igniter (usually just plugs into a receptical) and the coils (2 donut looking objects on the gas valve, replace both.) Access door may be on back if not on front, but normally their on lower right of front.

Dryer functioning but air not getting hot. this is a Maytag gas dryer


Hi,
Things that could stop a gas dryer from heating:
Glow bar igniter, thermal fuse (not all models), coils on the gas valve, gas valve, thermostats, motor heat switch, timer, selector switch, sensor.
On the back of the dryer near the fan blower housing is a thermal fuse, if this opens up (no continuity) the gas burner often quits but the motor will still run. If the thermal fuse is open/bad, always clean, change, adjust the venting system and vent hood first and clean out the dryer’s air ducts. Sometimes it is a good idea to replace the operating thermostat at the same time.
Thermal fuse parts help link...on blower housing cover, cannot be re-set, must be replaced if is open (no continuity between pins).
Thank you for contacting Fixya.com
